You might want to add a hot towel to the prep cycle. Say just before the lathering step. Best guess is to do that for at least 2 minutes.
As an example, I set the brush to soak in hot water, and put a little hot water on my soap, at the same time I've got a towel in the sink soaking in the hot water. I grab the towel, wring it out so that it isn't dripping, go to my easy chair in the living room kick back for five to ten minutes with the towel wrapped around my face, just like at the barbershop.
Is there an AD for towels?
